Jodie, who still had no idea about her brother's illness at this point, said his condition deteriorated frighteningly quickly.

"It all happened so fast, within the space of an hour. One minute he was still sharing things on Facebook, the next, doctors were telling my mum and dad that he was unable to breathe on his own," Jodie said.

"It was at this point that my parents called me at university in Lincoln and told me that I needed to come home straight away, we were told to prepare for the worst.

"Doctors have said that Ethan might not even remember coming to hospital, so I'm writing the diary for him to fill in the blanks.

"We've been told that patients in these cases can wake up with severe cases of PTSD, and having something to help them fit the pieces together of the last few days or weeks can really help their recovery."

Despite their ordeal, Jodie said doctors and nurses at both hospitals have been amazing in the care they have provided for her brother.

Ethan’s aunt and uncle, Nicola and Ben, have set up a Gofundme page to raise money towards ‘new legs’ for Ethan.

A statement made by them on the fundraising page says: “We are starting this fund raising to help Ethan and his family, as some of you will know Ethan is critically ill in hospital. Ethan had three cardiac arrests they confirmed he had sepsis. Ethan was sent for a scan of his chest to see if there was anything other than they thought as they had used a hand scanner.

“He was sent to ICU and put on lots of drips and machines he also had pneumonia and severe respiratory failure.

“On Monday 12th February he had to have his legs amputated to just below the knee. His full story and updates can be found in the links and will be updated as we get more news. Please help us to raise as much as we can for this special strong family and a special young man who has his full life ahead of him when he comes round. Prayers and well wishes always welcome.”
